An interactive, browser-based visualiser for nextpnr place-and-route results. Inspect the placement and routing of your FPGA design directly in the browser — no installation required. Part of the EDAcation open-source FPGA toolchain education platform.
Run nextpnr with the --write and
optional --report flags to produce the
JSON files, then load them here.
Use the routed.nextpnr.json file
produced by the
EDAcation VS Code extension.
This single file already contains the chip family, device, placement data and
timing report — no extra steps needed.
